Then I compiled and executed temper-tools according to instructions.
But there isn't any ttyUSB0. What should I do?
First, why do you think the device should appear as /dev/ttyUSB0? Is this in the documentation for the thermometer? Check this:
1. Make sure that the device is a stand-in for a USB to serial adaptor.
2. Make sure that the device is a generic
USB to serial adaptor, otherwise it may have a Windows-only driver.
3. Run this command:
# tail -f /var/log/messages
4. Now unplug and plug the device. Make sure the device connection leads to the creation of /dev/ttyUSB0 -- and your provided text shows that it doesn't.
I suspect that this is a Windows-only device and that it doesn't emulate a generic USB serial adaptor.
